expansion 1/N: flavor

We study the chiral condensate $textlessbarpsi psitextgreater$ for an SU(3) gauge theory with $N_f$ massless Dirac fermions in the fundamental representation when $N_f$ is increased from 2 to 6. For $N_f=2$, our lattice simulations of $textlessbarpsi …

Using lattice simulations, we study the extent of the conformal window for an $textSU(3)$ gauge theory with $N_f$ Dirac fermions in the fundamental representation. We present evidence that the infrared behavior is conformal for $12 leq N_f leq 16$, …
